3D Game Programming with directx 11 習題答案 8.3，programming8.3

第八章 第三題

1、將flare.dds和flarealpha.dds拷貝到工程目錄

2、創建shader resource view

HR(D3DX11CreateShaderResourceViewFromFile(md3dDevice,
    L"Textures/flare.dds", 0, 0, &mFlareSRV, 0));
 
HR(D3DX11CreateShaderResourceViewFromFile(md3dDevice,
    L"Textures/flarealpha.dds", 0, 0, &mFlareAlphaSRV, 0));

3、在Basic.fx中添加紋理

Texture2D gFlare;
Texture2D gFlareAlpha;

4、設置紋理

Flare              = mFX->GetVariableByName("gFlare")->AsShaderResource();
FlareAlpha          = mFX->GetVariableByName("gFlareAlpha")->AsShaderResource();

5、在Basic.fx中將兩個texel的值相乘（component-wise multiply）

float4 flareTex = gFlare.Sample(samAnisotropic, pin.Tex);
float4 flareAlphaTex = gFlareAlpha.Sample(samAnisotropic, pin.Tex);
texColor = flareTex * flareAlphaTex;

6、搞定

相對龍書時的相對基礎內容鋪墊，這回帶來的DX11感覺則大有不同了， Algebra詳細地過了一遍，原版Amazon上實在太貴，上店家印了出來，很聰明，分成了上下冊......
